For those interested in viewing those line printer files but without a suitable printer I have hacked together a small Java program for viewing and exporting the files. Nothing great, but it does the job. Try SMALLCAT first.
I understood that the first column contains FORTRANish line advance characters, but I am not sure what the "-" means. Nevertheless the result looks reasonable. A zip archive with a runnable jarchive and the source can be found at: http://www.mh-aerotools.de/downloads/LineArtPrinter.zip Martin
